11b55da700 powerpc: Fix oops when loading modules
This fixes a problem reported by Sean MacLennan where loading any
module would cause an oops.  We weren't marking the pages containing
the module text as having hardware execute permission, due to a bug
introduced in commit 8d1cf34e ("powerpc/mm: Tweak PTE bit combination
definitions"), hence trying to execute the module text caused an
exception on processors that support hardware execute permission.

This adds _PAGE_HWEXEC to the definitions of PAGE_KERNEL_X and
PAGE_KERNEL_ROX to fix this problem.

bc826666e4 powerpc: Fix ptrace compat wrapper for FPU register access
The ptrace compat wrapper mishandles access to the fpu registers.  The
PTRACE_PEEKUSR and PTRACE_POKEUSR requests miscalculate the index into
the fpr array due to the broken FPINDEX macro.  The
PPC_PTRACE_PEEKUSR_3264 request needs to use the same formula that the
native ptrace interface uses when operating on the register number (as
opposed to the 4-byte offset).  The PPC_PTRACE_POKEUSR_3264 request
didn't take TS_FPRWIDTH into account.

c7d07fdd5a powerpc: Print information about mapping hw irqs to virtual irqs
The irq remapping layer seems to cause some confusion when people
see a different irq number in /proc/interrupts vs the one they
request in their driver or DTS.

So have the irq remapping layer print out a message when we map an
irq. The message is only printed the first time the irq is mapped,
and it's KERN_DEBUG so most people won't see it.

7e875e9dc8 powerpc: Disable VSX or current process in giveup_fpu/altivec
When we call giveup_fpu, we need to need to turn off VSX for the
current process.  If we don't, on return to userspace it may execute a
VSX instruction before the next FP instruction, and not have its
register state refreshed correctly from the thread_struct.  Ditto for
altivec.

This caused a bug where an unaligned lfs or stfs results in
fix_alignment calling giveup_fpu so it can use the FPRs (in order to
do a single <-> double conversion), and then returning to userspace
with FP off but VSX on.  Then if a VSX instruction is executed, before
another FP instruction, it will proceed without another exception and
hence have the incorrect register state for VSX registers 0-31.

   lfs unaligned   <- alignment exception turns FP off but leaves VSX on

   VSX instruction <- no exception since VSX on, hence we get the
                      wrong VSX register values for VSX registers 0-31,
                      which overlap the FPRs.

4da727ae2a powerpc: Print progress of ibm,client-architecture method
The ibm,client-architecture method will often cause a reconfiguration reboot.
When this happens the last thing we see is:

	Hypertas detected, assuming LPAR !

Which doesn't explain what just happened.  Wrap the ibm,client-architecture
so it's clear what is going on:

	Calling ibm,client-architecture... done

In order to maintain the law of conservation of screen real estate, downgrade
two other messages to debug.

delayed works which want to rearm themselves will have to do that.  So it

e60f57f50f powerpc/math-emu: Change types to work on ppc64
While normally we don't use the math emulation code on ppc64 it can be
useful for doing things like emulating the embedded FP instructions.

Since performance isn't critical in this scenario its easier to keep
the sizes of the various math-emu the same as on ppc32.

bcd68a70cb powerpc: Hook up rtc-generic, and kill rtc-ppc
PowerPC has been a long time user of the generic RTC abstraction, so hook up
rtc-generic:
  - Create the "rtc-generic" platform device if ppc_md.get_rtc_time is set,
  - Kill rtc-ppc, as rtc-generic offers the same functionality in a more
    generic way, and supports autoloading through udev.

364fdbc00f spi_mpc83xx: rework chip selects handling
The main purpose of this patch is to pass 'struct spi_device' to the chip
select handling routines.  This is needed so that we could implement
full-fledged OpenFirmware support for this driver.

While at it, also:
- Replace two {de,activate}_cs routines by single cs_contol().
- Don't duplicate platform data callbacks in mpc83xx_spi struct.

6a11f75b6a generic debug pagealloc
CONFIG_DEBUG_PAGEALLOC is now supported by x86, powerpc, sparc64, and
s390.  This patch implements it for the rest of the architectures by
filling the pages with poison byte patterns after free_pages() and
verifying the poison patterns before alloc_pages().

This generic one cannot detect invalid page accesses immediately but
invalid read access may cause invalid dereference by poisoned memory and
invalid write access can be detected after a long delay.
